This is only used by mipi-dbi drivers so move it there.
The reason this isn't moved to the SPI subsystem is that it will in a
later patch pass a dummy rx buffer for SPI controllers that need this.
Low memory boards (64MB) can run into a problem allocating such a "large"
contiguous buffer on every transfer after a long up time.
This leaves a very specific use case, so we'll keep the function here.
mipi-dbi will first go through a refactoring though, before this will
be done.
Remove SPI todo entry now that we're done with the tinydrm.ko SPI code.
v2: Drop moving the mipi_dbi_spi_init() declaration (Sam)

Prep work before moving the function to mipi-dbi.
tinydrm_spi_transfer() was made to support one class of drivers in
drivers/staging/fbtft that has not been converted to DRM yet, so strip
away the unused functionality:
- Start byte (header) is not used.
- No driver relies on the automatic 16-bit byte swapping on little endian
machines with SPI controllers only supporting 8 bits per word.
Other changes:
- No need to initialize ret
- No need for the WARN since mipi-dbi only uses 8 and 16 bpw.
- Use spi_message_init_with_transfers()

spi-bcm2835 can handle >64kB buffers now so there is no need to check
->max_dma_len. The tinydrm_spi_max_transfer_size() max_len argument is
not used by any callers, so not needed.
Then we have the spi_max module parameter. It was added because
staging/fbtft has support for it and there was a report that someone used
it to set a small buffer size to avoid popping on a USB soundcard on a
Raspberry Pi. In hindsight it shouldn't have been added, I should have
waited for it to become a problem first. I don't know it anyone is
actually using it, but since tinydrm_spi_transfer() is being moved to
mipi-dbi, I'm taking the opportunity to remove it. I'll add it back to
mipi-dbi if someone complains.
With that out of the way, spi_max_transfer_size() can be used instead.
The chosen 16kB buffer size for Type C Option 1 (9-bit) interface is
somewhat arbitrary, but a bigger buffer will have a miniscule impact on
transfer speed, so it's probably fine.

The SPI event tracing can dump the buffer now so no need for this.
Remove the debug print from tinydrm_spi_transfer() since this info can be
gleaned from the trace event.

This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty
handler. All flushing will now happen in the pipe functions.
Also enable the damage plane property for all except repaper which can
only do full updates.

This change made ili9225_init() equal to mipi_dbi_init() so use it.
v3: Include vblank header (Sam)
ili9225 and st7586 can't use mipi_dbi_enable_flush() (David)
v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL

This prepares for the switch to drm_atomic_helper_dirtyfb() in the next
patch. The damage helper returns a drm_rect so switch to that everywhere
including using a pointer in the dirty functions.
This is a non-functional change except for the debug print which looks a
bit different.

The CMA helper now has the functionality to ensure a virtual address on
imported buffer so use that.

mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.
Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.
v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

Remove tinydrm_of_find_backlight from tinydrm-helpers.c. We now have
a generic of_find_backlight defined in backlight.c. Let the callers
of tinydrm_of_find_backlight call of_find_backlight. Also, remove
select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from
tinydrm/Kconfig as it is a hack that is no longer needed.
